Application tiled January 16,` 1926. Serial No. 8151372.y

My invention relates to a newand useful improvement in a combination primer7 fuel econonjiizer and humidiier adapted for use in internal combustion engines. One of the objects of the invention is the provision ofa device of this class which may bel quiclrl, and easily attached on a vehicle having an internal combustion engine for propelling the saine.

- Another object'of theinvention lis the provision of ay mechanismot this class whereby a volume of combustible ruelinay be delivered directly to the combustion chamber for priming purposes, through a simple and easyl operation ofthe mechanism. j

Another object of the invention is the provision ogt a device of this class whereby a quantity of air and water mixed together to form a moist vapor may be delivered to the internal combustion engine with a resultant saving intuel and an increasein operating eiiiciency. v V

Another Objectis the provision of a device of this class whereby the nature of the fueldelivered to the combustion chamber may be controlled so that an easy and smooth running 'motor is effected. o Other objects will appear hereinafter..

. The invention consists in the combination and arrangement yof parts hereinafter de-V the` cylinder upon movement ofy the the opposite direction.

scribed and claimed. j

The invention will be best understood from a reference to the accompanying' drawings which form a part of this specification and in which Fig. 1 is a vertical central sectional view ot the mechanism taken on substantially line 1 1 of Fig. 3. y

Fig. 2 is a 'sectional view taken onsubstantially-line 2-2 of Fig. 1. Y j f A Fig. 3 is a. front elevational view of the plateand n'iechanisin mountedupon-and projectirig through the supporting body.

As shown in the drawings there is mounted upon the dash Qrotthe vehicle with which used an instrument plate having graduations 11 tmmedthereon and otherindicating,inatterto `indicate the direction oftu'rni-nfir of the various operating mechanism. 4Positioned in an opening 12 formed inthe dash V9 is a tubular member 13 which is projected through an i opening formed in the plate 10 and provided with a lock nut 14` engaging the outer surface ot' the piate 10 and withv a loclrnutl engaging the inner surface l the dashl 9. T .hreaded upon the tubular member 13 is a housingl 1n .whichis threaded thethreaded portionl?. of

thepriming rod 18, Whiclrprojects through thev caplQ threaded .onthe outer endof the tubular member 13, `this cap 19 having an air rehel' opening 2O formed therein. Mounted uponthe outerendof therod 18 is a knob or hand-hOld 21.., Positioneduponthe rod 18 isfa sleevej22 having at one end a headA 23. Mounted upon the sleeve 22 is a plunger guide and spacer V24.' lPositionedbetween the plunger guide and. spacer 24k andthe sleeve head 23 is a leathercup 25. 4GIhreade'd ony the sleeve 22 is a nut 26 which serves to bind against the plungerguide and spacer24 a leathercup 27. This nut ,26 serving to bind the leather cup 25 againstthe head v23 so as to clamp -it between the head2?) and theplunger guide or spacer 2d, Pins 28and29 are projected 1through' lthe rod 18 to .properly locate. theposition of the sleeve 22 thereon. The 'constructionis.such that when the threaded portion 17 is disengaged from the threads f of the'housing 16 the rod 18 maybe used for nimping purposes, the tubular member 13 forming the` cylinder and thev leather cups forming the piston. Itis evident that on the rctractive movement of the piston the air will be forced outwardly from thefopening 20l which is formed inthe cap 19, and that Vthis opening 2O Will permit the entry ofV air into piston in A 'seat 30. is formed in the housing for re ceivingthe end of therod. 18 which isformed to provide-a needle valve. A passageway 31 leads from the seat 30 and connects with the opening formed kin the seat@ forming bushing 32 Whichis threaded into the p1ugv33, which isscrewed into the housing 16. Connected to the .plug 33is a delivery pipe 34 which connectswitha T 35 projecting outwardly from vwhich. is a pipe 361carrying onitsv end a nozzle 37 having a pluralityof emission passages 38 and 38fforined therein. It will be noted that the outleto-these emission passagesare extended in differentdirections. lCon'nectedto the T 35-V is anothery pipe 39 which I connects tothe L 10 projectingfromwhich.isfthe pipe 41 carrying a nozzle 112 constructedsimilarto fthelnozzle 37.A` Itis believed evident that any .number of nozzles `may beusedy as desired,

these nozzles beingl'projected in.4 any suitable manner into the intake manifoldofthe e`n` gine `bet-weenthe `engine andthe carburetor. The chamber 43, which is-formedli'n thehousing l'fcominunicates' through the passage 44 with the chamber 45 formed` in tliefplug 46 which is threaded into the housing 16.7 This .f

plug 46 communicates by means of tfhefpas-v sage 47 with a. pipe 48 connected to a T 49 Which communicates bythe pipes 50 and 51 with the sourceiof.fuclsupply. APositioned f in the chamber 45 is a ball 52 which in one position serves as a closure for the passage 46'- so as to prevent communication of this pas sage 46 With:V the chamber 45.- A pin 53 ris' *f projected across thechamber 45 so as to pre- 4plug 56 having a passage 57 formed therein so that when the cocl plugis turned by means Yof the rod 58 Whichcarries the indicating orY operating handle 59, to the position shown in Fig; lthe chamberf43 Will rbe inl communication with the Vsource* of fuel "supply,y It vis evident that upon retracting'the .piston in the tubular memberl the ball will? move to position so as to close communication bet-Ween the tubular member 13 andthe delivery `pipe 34, -ivhile at the same. time thevvballL 44 Will "be liftedv from its seat to permit communica-' tion between the cylinder l forming tubular member andthe source of 'fuel supplyythus permitting the piston to draw into the tubular member 13`fa. supply of fuel; Upon movement lof -the piston in the opposite direction the ball 44 will serveto close communication be'-4 tvveenf the cylinder' I3 andthe source `of fuel supply and the ball 5,5'Will7'move from its seat to permit: the passageU of -the= fuel from 'theicylinder 13 to tlienozzles 37 and 42; f In v gine is effected". y

extension' 58 1s formed' on thev housing this Way a quick and easypriming'of the en- 46,'thisextensionibeing connected to the housing 46' by a neck 5`9` through which 'projects a passage communicating With'the passage '57 by the passage 61 formed inI thecock plug 56; Formedini the neck 60 andf communicating with thejpassage 59 is a passage 627Which communicates withl theatmosphere and permits the entry ofiajir into the passage KA60 and thence' through the passage 57 into thedelivery pipe3`4, by'vvay'of the cylinder 123.' "It,

will benotedfrom 2 that the cock yplug 56 may be rotated? so that the: air maybe drawn intothe pipe=34 at the'same time that water isf draavirtherein and ,that at the ,Will of the operator Vtl`ie` 'ga`s1l ailon'e'may be drawn into 1 theeyiiader 1e.

Positioned 'inthe' extension `58-is a cockplug I 63 which is operated by th-erodj (i4-carrying the operating handlei'. "This extension `58 communicates by the nipple `66-ivith a suitable rhousing I6 so that it remains stationary. The

hand'hold or indicator 59 is then moved tothe position soa-s to close the Connection between the delivery pipe 34 andthe source offuel supply. This will be effected by turning'theV` 4stop cock plug56 as shown in FigQin a clock- Wise direction throughninety degrees. This y will leave thedelivery pipe 34 in oonditionlfor communication Witlithev air supply-paysage 62 and if desired,.upon a proper rotationof the coclrplug 63, With the Source of Water supply so that the engine vWill'fdravv into the intake manifold a mixture cfa-ir and Water- When it desired't'o'draw into the intake manifold air onlytli'eV cock plug 63 Will'be turned so as tosliut'off thefsupply of Water. Vhenused in this manner the device operates as a fuel economizer supplying a larger amountlof'air tothe fuel mixture and thus thinning it out with theconsequent savingI results in the consumption-of fuel f g l The vWater control maybe moved so asfto permit thel ent-ry of Water in small degrees, as by a drop at a time. Such an arra''ngement y Will humidify the fuel mixture and' afford an 'easy and speedy runningmotor giving the sameefect as is ordinarily produced in a motor Whendriven inthe night time or ina damp atmosphere. Upon admission of a larger shown, but desire to avail myself of such variations and modifications as come within the scope of the appended claim.

f Hming thus described my invention what n I claim as new and desire to secure by Letters Patent iszf f amount of Water byproper regulation of the 'i Ina'deviceof the class described adapted o for use on vinternal lcombustion 'engines having an kintake manifold, comprising: ejector ifnozzlescommunicating Withsaid manifold; a n

.delivery pipe communicating at one end with saidy nozzles; ahead connected to said delivery vpipe atthe opposite end, saidfhead having a plurality of passages formed therein in coms `munication With said delivery pipe; a cylinder communicating with said" passages; a piston slidably mounted in said cylinder; e piston rod connected to saidpiston and extending at one end exterior-ly of Said cylinder' and project-ing beyond said piston at the opposite end, said opposite end being tapered to forni a needle Valve, a portion of said opposite end nterme diete said piston and said needle Valve forniing portion being threaded into said head; a Water conduit connected to a suitable source of Water suppl)7 .and Communicating with passages in said heed; a fuel conduiteonneeted to a suitable source of fuel supply and communicet-ing Wit-h said passages in said head, said head having an air passage communicating with the atmosphere, the needle valve forming portion of said rod being adapted, upon a threading of said rod in said head, for controlling eolnlnunieation of said deliverypipe With said sources of fuel, and Water supply and the air. y

In testimony whereof, I have Signed the foregoing. A
